API 650 cylindrical welded storage tanks examiner
BBN can provide design, manufacture and installation of API 650 large oil and crude oil storage tanks. We can build a API 650 cylindrical welded storage tanks 7,000,000 gallon API 650 petroleum storage tank. In addition, BBN has the means to construct multiple storage tanks at the same time. We are very experienced in providing API 650 petroleum storage tanks.
BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t–c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t–c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API 650 cylindrical welded storage tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
Sand blasting and derusting of API 650 cylindrical welded storage tanks uses compressed air as power and SiC, pomegranate sand and quartz sand as spraying materials to form high-speed jet beam, which is used to remove rust and dirt on the surface of metal storage tank and improve the binding force of workpiece with coating and plating material. Sand blasting is often used in API 650 cylindrical welded storage tanks construction.
